Final answer:
The depth after 3.6 minutes is 37.44 meters.
Step-by-step explanation:
To find the depth after 3.6 minutes, we can use the equation:
Depth = Average Speed x Time
Given that the average speed is 10.4 m/min and the time is 3.6 min, we can substitute these values into the equation:
Depth = 10.4 m/min x 3.6 min = 37.44 meters
